Question

我试图从内容视图中隐藏smallIcon，而不是从状态栏隐藏。首先，我试着通过编写以下代码来隐藏它：

.setSmallIcon（android.R.color.transparent）

但状态栏中也看不到小图标。

然后我尝试了：

using System.Windows.Controls;
using System.Windows.Input;
using System.Windows.Interactivity;

public class DisableDoubleClickBehavior : Behavior<Button>
{
    protected override void OnAttached()
    {
        base.OnAttached();
        AssociatedObject.PreviewMouseDoubleClick += AssociatedObjectOnPreviewMouseDoubleClick;
    }

    private void AssociatedObjectOnPreviewMouseDoubleClick(object sender, MouseButtonEventArgs mouseButtonEventArgs)
    {
        mouseButtonEventArgs.Handled = true;
    }

    protected override void OnDetaching()
    {
        AssociatedObject.PreviewMouseDoubleClick -= AssociatedObjectOnPreviewMouseDoubleClick;
        base.OnDetaching();
    }
}

但它没有用。请指导我。提前谢谢。

    NotificationCompat.Builder builder;

      builder = new NotificationCompat.Builder(getApplicationContext())
                    .setSmallIcon(getNotificationIcon())
                    .setContentTitle(getResources().getString(R.string.app_name))
                    .setWhen(System.currentTimeMillis())
                    .setContentText("New Message");

//get custom layout
             RemoteViews notificationView = new RemoteViews(
                            getPackageName(),
                            R.layout.new_notification_card_layout
                    );
                    notificationView.setImageViewResource(R.id.notification_image, ResourceId);
         notificationView.setTextViewText(R.id.title, title);

        builder.setCustomBigContentView(notificationView);


     public int getNotificationIcon() {
            boolean useWhiteIcon = (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP);
            return useWhiteIcon ? R.drawable.notification : R.drawable.notification_teal;
        }
